My dealer called their special service line, they said kia knew about the vibration and replaced mine.
Ask the dealer call them

Yeah am going to do that, the Genesis recall came out today

Have my appointment on the 22nd for vibration issues. As well as a nasty bucking from the transmission

Has Kia Recalled the tires yet I was planning on replacing them when my snow tires came off but if Kia will for free I might not be so quick to the draw

We will see next friday when I take it in lol

i notice that vibration on mine too it has hankook optimo h426 tires. they vibrate and wobble for a bit and i guess when they heat up it stops. the salesman said it was because the car is so heavy, but i wonder if it is something with hankook tires

Yea, I assume it to be the hankook tires. They are rated very very poorly online.

The more I read these comments about Hankook vibration the more I know, when I pull off my Falken snows, I will buy dedicated summer titres .. My first inclination is to investigate Falken summer Tires .I have their winter tires and they are very quiet , in fact less noise then the Hankook .Any suggestions g out there although I am probably two months too early

Being the first time I took our K9 on the freeway I did notice vibration starting at about 60 mph. I did kind of notice it before but not really thought about it.

I personally normally change to Yokohama tries anyway, personal preference so expect I will do the same.

My K900 also vibrates.
